Need help using Socat to use z-wave usb stick over network

[Evelen]

This is the deal:
I have two USB devices I have connect to a server, but will use on another server.
 
The server which are connected physical with the USB sticks are a raspary pi, the Domoticz server I use them on is a 64bit virtual ubnutu server.
 
The two units are as follows:
1. RFXtrx433E http: //www.rfxcom.co...nsceivers/14103
2. UZB1 https://www.z-wave.me/index.php?id=28
 
On the Pi I have isntalled and configurated ser2net. and added the following to ser2net.conf

Code: Select all

10001:raw:0:/dev/ttyUSB0:38400 8DATABITS NONE 1STOPBIT
10003:raw:0:/dev/ttyACM0:38400 8DATABITS NONE 1STOPBIT

10001 is RFXtrx433E, this I know works because In Ubuntu server I use the RFX-over-IP feature.
But Domoticz does not support using UZB1 directly on IP, so I must therefore emulate it as a local unit of ubuntu.

I hear Socat should be a good program for this, but I get it simply not to work.
 
Here are device pi-one:

On Ubuntu / Domoticz server I have tried a bit of everything:

Code: Select all

flemmingss@VM4:~$ sudo socat pty,link=/dev/UZB1overIP,raw,echo=0 tcp:pi1:10003

flemmingss@VM4:~$

So, how do I get this to work?
"pi1" is the hostname for pi

I found out the listning of port 20001 was missing

Code: Select all

root@pi1:~# ss -lnp | grep ser2net
tcp    LISTEN     0      1                      *:2000                  *:*      users:(("ser2net",pid=340,fd=4))

tcp    LISTEN     0      1                      *:3000                  *:*      users:(("ser2net",pid=340,fd=6))

But after running this command it worked:

Code: Select all

ser2net -p 10002

But I need to run this everytime I reboot the pi...

Also, the socat dommand on domoticz server works and I cant add the UZB1 interface in domoticz, but ut don't work.
0 nodes.
also, it looks like it realy dont work, no blinking blue in the USB stick when scanning for incklusion or other things.
When I put it back directly in the domoticz server it works.
